SHROUD NOZZLE FOR CONTINUOUS CASTING

摘要

PURPOSE: A shroud nozzle for continuous casting is provided to obtain an extended service life by reducing damage due to air pressured increased by molten steel. CONSTITUTION: A shroud nozzle for continuous casting comprises a body(15a) and one or more reduction holes(15b). The body is coupled to the bottom of a ladle and extended to the inside of a tundish(20) to be dipped in molten steel contained in the tundish. The lower part of the body, which is dipped in the molten steel, has a greater diameter than the upper part coupled to the ladle. The reduction holes are bored through the body and located above the dipped part of the body in order to discharge the internal air of the body to outside. The reduction holes are formed in symmetrical positions of the body.
